Direct Transfer to the Neuroangiography Suite for Patients With Stroke

Abstract

The therapeutic focus in acute ischemic stroke over the last 2.5 decades has been to balance the benefits of rapid reperfusion therapy with the risks of treatment-related complications. Both intravenous thrombolytics and endovascular thrombectomy are proven to substantially improve outcomes in a time-dependent manner. Each minute saved in achieving successful reperfusion grants an additional week of healthy life and may salvage up to 27 million neurons. The current approach to patient triage is inherited from the preendovascular thrombectomy era of stroke care. Current workflow concentrates on stabilization, diagnosis, and decision-making in the emergency department, followed by thrombolysis if eligible and subsequent transfer to the angiography suite as needed for further treatment. Multiple efforts have been directed toward minimizing the time from first medical contact to reperfusion therapy including prehospital triage and intrahospital workflow. Novel approaches for stroke patient triage such as the direct to angio approach, (also referred to as One Stop Management) are currently in development. The concept was initially introduced as several single-center experiences. In this narrative review article, we will consider various definitions of direct to angio and its variants, discuss its rationale, review its safety and efficacy, assess its feasibility, and delineate its limitations. Further, we will address methods to overcome these limitations and the potential impact of emerging data and new technologies on the direct-to-angio approach.
